A few things to try:
- are all USB devices unplugged?
- Clear the CMOS with the jumper or by removing the coin sized battery for about 15-20 minutes
- take it down to basics. CPU, 1 stick known working ram, video. Everything else unplugged or taken out of the slots.

When you plugged in your v-touch, you may have overloaded the USB port, as it shut down at that moment. The overload may have damaged something else on the motherboard, but make sure the video card actually works on another machine - it may be the problem.
